Schematic shows R4 at the emmiter of the transistor, as amb and majkel have suggested it should be between the opamp and transistor, this is also the correct configuration in the canamp. The amp i managed to get a look at has been modified and has had the.... -
The circuit is designed to run off a 100k volume pot, and be either a line stage or a headphone amplifier. It is a standard non-inverting gain stage (A=15dB) followed by discrete copy of the old LH0002 buffer IC. The basic idea is that the four transistors.... -
A unit which is often very useful, if we need to isolate, in sound circuits, two stage between them. Then we can use this circuit which has an amplified unit, which gain X1, we do not use total negative feedback, only local, with the result that distortion.... -

The current sourcing/sinking capability of the I/O pins on Raspberry Pi is quite limited. According to the Wiki page, the current limit for each I/O block (e. g. GPIO0 through GPIO27 combined) comes at only 26 mA maximum, which is only capable of driving a.... -
There are situations in which very long cable runs are necessary from the pedalboard to the amplifier, or a more powerful driving circuit is needed to the heavy load presented by devices in parallel. A good buffer box is the solution. The best buffer board.... -
Boosters are not buffers! While it is possible to make a booster that also provides a buffering action, the vast majority of the boosters commercially available ready-made or kits, do not have the proper design to be buffers. A buffer should have a high.... -
The wah will work before the amplifier but sounds very low in volume and it sounds scratchy when the wah is rocked back and forth. The wah is fine without the buffer. In front of a fuzz face, with the fuzz face on, no sound passes Bizarre indeed. I`m going.... -
This is the complete schematic for the circuit that is contained on the AMZ Multi-Purpose PC Board. None of the example circuits will utilize every part that has been positioned on the board. Extra parts have been included to add flexibility and options to.... -
When designed with general purpose small-signal transistors, the bandwidth is 50MHz to 250MHz so very careful grounding and power supply decoupling is required. Simulation schematic for 2 transistor buffer. *Copyright Poul Petersen 2009 * *Some standard.... -
The TMB-1 is an RF amplifier unit / receiving accessory that can be used with a low-impedance broadband loop, a high-impedance terminated loop (such as a Pennant, Flag, or Kaz Delta), and whip (telescoping rod) antennas. This particular design is optimized.... -
It`s basically a standard Hartley oscillator, output is +7 dBm into 50 Ohms. Don`t be tempted to add a gate diode, this circuit doesn`t need it, and it will degrade the phase noise performance, according to Ulrich Rohde. It should be suitable for any.... -
This circuit makes a nice, clean preamp or a clean booster pedal. It is not designed for overdrive, but is designed to be overdrivable. If overdriven, it provides the kind of soft clipping one may expect from JFETs, but it is not optimized to be generally.... -
Need some program to set it`s channels to the maximum level, or write the full scale to the DAC. Looking at the MD schematics, you`ll see that the audio is mixed together with relations of 0. 0431 for the PSG, 1 for the YM and 0. 0468 for the external audio.... -
Buffer amplifier is required by a typical pH probe to isolate its 10^6 to 10^9 ohm source resistance from external circuitry. Such an amplifier is shown in the.... -
This is a buffer circuit for TMP01 Temperature Sensor. The output of this sensor is a low impedance dc output voltage with a 5 mV/K temperature coefficient.... -
Buffering for the zener is provided by the impedance matching and current amplifying characteristics of the emitter follower and draw less current from it. To.... -
This is a phantom-powered FET preamplifier built into a 1/4" guitar cable, similar to the one on the Tillman site. There are only a couple of parts to the amplifier, so the difficulty was being able to trim and solder component leads to fit within the space.... -
In some versions you don`t have the input buffer at all, and in some versions the buffer transistors have different biasing or different transistors. Some have even BIG errors. Errorswith the biasing, errors with the transistor symbols. I understand that the.... -
The solid-state, unity-gain power buffer is easy to imagine, as many already exist. But what about corresponding tube equivalents Have they been made Could one be made Actually, super cathode followers (complex-and-augmented cathode followers with a gain of.... -
Most people who want to modify and improve their Spectrum look first at the keyboard as a prime area for change. But straightforward replacement involves digging around inside the computer - something of a put-off, for two important reasons. To begin with it.... -
Using this circuit you will connect to a single parallel port electronic circuits requiring up to 96 digital output, optically insulated lines, 3 to 15V powered. The CD4094B consists of an 8-bit shift register and a 8-bit latch. Data is shifted serially....

The sub-harmonic bass generator is a sound producing unit for guitars. The sound it produces looks very much like that of the bass guitar. The octave generator is sometimes quite unusual since it does not produce any of the usual ways of coloring the sound,.... -
In the past the sounding (sea bottom measurement) was done with the "bullet", that is, with a heavy lead object that the seamen plucked into the sea hung from a calibrated rope. As soon as the "bullet" reached the bottom, the depth appeared directly from the.... -
This Amplifier was designed to have the following specifications: Distortion less than 0.1% at full power of 100W even at 20KHz. Power has to be attributed to an extended bandwidth. The output transistors must be protected against short circuits. The power.... -
A series of LEDs serve to alert the gardener when plants need water. Using two conventional digital integrated LEDs and a series of LEDs, we make a very useful device for gardening. The device detects the amount of water in the pot and alerts the grower.....
